Barcode Encoder In None Using Barcode encoder for Software Control to generate, create bar code image in Software applications. Whenever current flows through a resistance, heat results. The heat can be measured in watts (symbolized W) and represents electrical power. (As a variable quantity in equations, power is denoted by the uppercase italic letter P.) Power can be manifested in many forms, such as mechanical motion, radio waves, visible light, or noise. But heat is always present, in addition to any other form of power, in an electrical or electronic device. This is because no equipment is 100 percent efficient. Some power always goes to waste, and this waste is almost all in the form of heat. Look again at Fig. 24. There is a certain voltage across the resistor, not specifically indicated. There s also a current flowing through the resistance, and it is not quantified in the diagram, either. Suppose we call the voltage E and the current I, in volts (V) and amperes (A), respectively. Then the power in watts dissipated by the resistance, call it P, is the product of the voltage in volts and the current in amperes: P = EI If the voltage E across the resistance is caused by two flashlight cells in series, giving 3 V, and if the current I through the resistance (a light bulb, perhaps) is 0.1 A, then E = 3 V and I = 0.1 A, and we can calculate the power P in watts as follows: P = EI = 3 0.1 = 0.3 W Suppose the voltage is 117 V, and the current is 855 mA. To calculate the power, we must convert the current into amperes: 855 mA = 855/1000 A = 0.855 A. Then: P = EI = 117 0.855 = 100 W DataMatrix Creation In None Using Barcode generation for Software Control to generate, create Data Matrix image in Software applications.

Recognizing USS Code 128 In Visual Basic .NET Using Barcode decoder for .NET Control to read, scan read, scan image in Visual Studio .NET applications. You will often hear about milliwatts (mW), microwatts ( W), kilowatts (kW), and megawatts (MW). By now, you should be able to tell from the prefixes what these units represent. Otherwise, you can refer to Table 22. This table lists the most commonly used prefix multipliers in electricity and electronics. Sometimes you need to use the power equation to find currents or voltages. Then you should use I = P/E to find current, or E = P/I to find voltage. Always remember to convert, if necessary, to the standard units of volts, amperes, and watts before performing the calculations.

Have you noticed some strange things about the notation yet If you re observant, you have! Why, you might ask, are italics sometimes used, and sometimes not used Something should be said early in this course about notation, because it can get confusing with all the different symbols and abbreviations. Sometimes, symbols and abbreviations appear in italics, and sometimes they do not. You ll see subscripts often, and sometimes even they are italicized! Here are some rules that apply to notation in electricity and electronics: Symbols for specific units, such as volts, amperes, and ohms, are not italicized. Symbols for objects or components, such as resistors, batteries, and meters, are not italicized. Quantifying prefixes, such as kilo or micro, are not italicized. Labeled points in drawings might or might not be italicized; it doesn t matter as long as a diagram is consistent with itself. Symbols for mathematical constants and variables, such as time, are italicized. Symbols for electrical quantities, such as voltage, current, resistance, and power, are italicized. Symbols and abbreviations for modifiers might or might not be italicized; it doesn t matter as long as a document is consistent with itself. Numeric subscripts are not italicized. For nonnumeric subscripts, the same rules apply as for general symbols. Some examples are R (not italicized) for resistor, R (italicized) for resistance, P (italicized) for power, W (not italicized) for watts, V (not italicized) for volts, E or V (italicized) for voltage, A (not italicized) for amperes, I (italicized) for current, f (italicized) for frequency, and t (italicized) for time.
